Switch Calc is an app to make it easier for Individuals with a physical disability to perform simple math calculations using only a single button (switch). The input is handled by doing an automatic section/item scan using a large on-screen button.

This app is targeted to help phone/tablet users who struggle with touch accuracy either due to range of motion or dexterity issues. The on-screen button (switch) accounts for greater than 30% of the total screen area to minimize input errors or erroneous touches.
